In Thailand, holding wedding ceremonies for fraternal twins had run for a long history because they believed that fraternal twins were lovers who failed to stay with each other during the last life.
Since the couple didn't embrace sweet life in previous incarnations, they need to stay with each other this time. Therefore, at the young age of the twins, the boy should marry his sister. Otherwise, the twins may be forced to separate once again or suffer from diseases or bad lucks.
